Impact of Privatization of the Nigerian River Basin Authorities on Water Use Efficiency (Published)

The study examined the impact of privatization on efficiency of water use in selected irrigation schemes under the Lower Niger River Basin Development Authority of Nigeria. Government policy is aimed at achieving food self-sufficiency through the proposed privatization of these schemes hence making water an economic good whose use will thus be levied more rationally. Data was drawn on 414 small-scale irrigation farms under the two existing tenure Systems in 7 irrigation schemes in the basin. The DEA results showed that on the average, substantial overall inefficiencies characterized the farms in both the User Allocation and Farmer Occupier tenure systems. Unlike the situation in the rice farms, vegetable and maize farmers under the Farmer Occupier System demonstrated considerably higher levels of efficiency than those in the other system. For the vegetable farmers, it was a switch of value dominance between the CRSTE and the VRSTE. The result of the price simulation showed an irregular pattern of marginal efficiency change in all the DMUs of both systems. This result frowns at the proposed privatization, should the new investor transact resources in a way that is not at par with the prevailing open market condition thereby overshooting the margins of farm-level efficiency.

Adoption of audit software by Small and Medium-sized Practices in East Africa (Published)

Purpose: Information technology has been implemented by organizations in East Africa with most transactions and records being digital. At end of the financial year, these organizations require their financial statements to be audited. This study was to first take stock of the level of adoption of audit software by Small and Medium-sized Practices (SMPs) in East Africa. This comes at a time where the Covid-19 pandemic has led to even further computerization as organizations implemented health directives on face-to-face contact, paperless environment and work-from-home initiatives, among others.  Methodology: A questionnaire comprising seven questions were sent out to sampled firms to respond electronically via the SurveyMonkey® tool. Out of about 1310 firms, the questionnaire was sent out to a random sample of 700. Results:  A total of 251 responses were received (36% of the sample). 70% of the SMPs were 1-10 years old in practice. Only one-in-four firms (25%) had adopted audit software. The four most common audit software were CaseWare®, Myaudit, PCAS and DraftWorxTM. The three major benefits from using audit software were the improvement in audit quality, audit project efficiencies and IFRS-compliant accounts. The three main challenges faced in adoption of audit software were the high costs of the software licenses, the lack of timely vendor support and the unstable/high cost of internet connectivity. The three main suggestions to increase adoption of audit software by SMPs in East Africa were to compel all the firms to adopt, to lower the cost of the software and probably develop a home-grown solution. Significance of study: The study has helped highlight the extent of adoption of audit software. It has also revealed the most common audit software in use. With this information, the NBAAT, ICPAK, ICPAU, iCPAR and OPC can develop a 3-year roadmap to facilitate the SMPs to gradually acquire the audit software. At each Annual Practitioner’s Forum, adoption of audit software and how it enables the firm’s business to grow can become a permanent topic. This can supplement the advanced Microsoft Excel® training that is being undertaken by most of the SMPs. Future research: After a 2-year period, further research can include an in-depth interview with a sample of firms that responded to determine the influence of audit software or lack thereof on their competitiveness among fellow SMPs in their respective countries.

Contribution of community conservation projects on improved livelihoods, and sustainable biodiversity conservation in Nyungwe National Park (Published)

Recently, Rwanda Development Board (RDB) has established a revenue sharing scheme (RSS) to create a win-win approach in protected areas for effective biodiversity conservation and management. Through this scheme, around 1 billion Rwandan francs were invested to support around 152 Community Based Conservation Projects (CBCs), and integrated conservation and development projects (ICDPs). This paper assessed the contribution of conservation projects around Nyungwe National Park (NNP). It evaluated their efficiency and effectiveness, and their socio-economic impact to the local community development. Secondary data about the revenue sharing projects and the amount of money allocated to each project were collected from RDB office. Primary data were collected through the interview and focus group discussion. To verify the findings from RDB, interview and focus group discussion (FGD) were used. Interview was done with local peoples around Nyungwe National Park and with community conservation wardens, while threats to NNP were verified by the consultation of reports from ranger based monitoring officers. The results showed that the value of resources collected by people from the park is higher than the revenue sharing support offered by RDB and consequently the revenue sharing scheme did not significantly reduce threats to biodiversity and its impact around NNP. We recommend the revision of the whole revenue sharing scheme, taking into account the cost of livelihoods of community surrounding the park.

Profitability and Marketing Efficiency of Smoked Fish: An Empirical Evidence from Ondo State, Nigeria (Published)

The level of efficiency and profitability of the market and marketing functions are very important for sustainable marketing of agricultural products like fish. To ensure continuous availability of fish for human consumption, nutrition, and wellbeing, the Nigerian economy requires effective and efficient marketing systems. Fish marketing serves as a medium for bridging the gap between producers and consumers of fish. The study considers 80 fish marketers from Ondo state using purposive sampling technique. The data collected for the study were analysed using budgetary technique and shepherd efficiency model. The study revealed that fish marketing is profitable with gross margin of #38,101.36 and 15k as return on investment. The shepherd efficiency model revealed that fish marketing activities among fish marketers is highly efficient with efficiency value far higher (558.0%) than 100% deducing that an increase in the cost of performing marketing service (that is added time, form and place utility) by 100 percent will give a more than proportionate increase of 458.0 percent in the level of satisfaction derived from a kilogram of fish sold in the market. It was recommended that government should focus on policy that encourages farmers and young graduates in the business as it is noted for profitability, efficiency and a source of livelihood.

Impact of a Cognitively Modified Instruction on Vocabulary Acquisition of Second Language Users of Grade 2: A Study Conducted in a Private American School in Dubai (Published)

This experimental study was conducted to find the impact of modified instructional strategies on the vocabulary and reading comprehension skills of grade 2 (7 year old) students of English as second language.  The main research question was that how will the cognitively modified instruction impact the vocabulary acquisition of grade two students with Arabic as first. The research hypothesis was that if the instruction in class is designed to help students acquire vocabulary skills while the cognitive load is reduced during the learning process, it will result in improved performance (Cooper 1998). To test the hypothesis, specific instruction was tailored using principles of split-attention effect, modality effect, and redundancy effect to reduce the cognitive load. The experiment group was exposed to modified instruction for four weeks, 50 minutes lesson each day. Deviation method was used to analyse the impact of modified instruction on students’ performance. Results on performance and mental effort tests of the experimental group indicated that reduced cognitive load helped increase the performance of students in vocabulary and comprehension acquisition.  Efficiency metric showed that students in experiment group demonstrated better efficiency as compared to the control group. Lesson observations were conducted to validate the delivery of the instruction as per the design. The findings of the observation reflected a higher level of student engagement. The study concludes that modified instruction with reduced cognitive load results in increased performance of the learners of the English as a second language.  The key theories consulted were theory of evolution, cognition, schema, and cognitive load theory.

Joseph Conrad’s Heart of Darkness: Debunking the Two Basic Imperial Clichés (Published)

Joseph Conrad’s in his Heart of Darkness has been condemned as a supporter and defender of the imperialist views and in other situations he is thought to be ambivalent, ambiguous and indecisive concerning this same topic. This paper aims at proving that in Heart of Darkness Conrad employs strategy of introducing the long established imperial clichés to debunk them and to show how fake they are. This strategy is successful and convincing in depicting the cruelties that are caused by the power and authority of imperialism especially if we put this novel within its historical context; a time when imperialism and all of its byproducts were acceptable as practices of the white man’s burden theory

Assessing the Efficiency of Soya Bean Marketing In the Ejura-Sekyedumasi and Nkoranza South Districts of Ghana (Published)

The study aimed at assessing the efficiencies of soya bean marketing channels in the Ejura-Sekyedumasi and Nkoranza South Districts, Ghana. The multi-stage sampling technique was employed in selecting thirty-seven soya bean farmers, two wholesalers, seven retailers, two small-scale processors and one large-scale processor of soya beans for the study. Gross Margin analysis was employed in determining the marketing costs and margins whereas the Shepherd’s Method was used in analyzing the efficiencies of the marketing channels. The study revealed that nine different channels existed through which soya bean was marketed in the study areas, with the simplest channel (Channel 1) being where farmers sell directly to consumers. Analysis of marketing cost and margins revealed that comparatively, Channel 1 had the least cost (GH2.40) and margins (GH10.50) since farmers dealt directly with consumers without any interference from market intermediaries, who usually increase transaction cost. From the study, Channel 1 was the most efficient channel with an Efficiency Index of 37.71. Thus, its marketing cost constituted a smaller proportion of the consumer price. The study recommends that farmers use Channel 1 where they sell directly to consumers to market their produce and also form co-operatives to protect them against price fluctuation and give them assurance of buyers. Moreso, the central government is directed to intervene in the form of road construction and improvement to help reduce the excessive transportation cost associated with the soya bean trade in Ghana
